Question about Water Heaters
Hi, we recently replaced our trianco tr45 burner with a parkray 99 (both smokeless fuel). The old burner used to make the house fabulously warm and heat the water so hot we had to run it off to stop the pipes banging when it boiled, the new burner seems much safer (boiling water was scary lol) but doesnt seem to heat the water or the house anywhere near as well.
We have the correct number of radiators for the model (3 less than max) but when we get the fire banked up high and turn on the pump it doesnt heat the radiators as well as the old one did (no air bubbles but just not as hot as they were) and it seems to take ages to heat them up.
When we turn the pump off to heat the water for a bath properly (as instructed in the manual) the radiators go stone cold in about 5 minutes, so the house gets cold, and with the pump on the water wont go above luke warm really. With the old burner we never needed to turn the pump off because the water was always hot anyway.
Should this be happening?
We seem to have a choice of nearly hot water or a nearly warm house.... seems we cant have both. Are we doing something wrong?
The heat seems to all stay in the burner, not much transferring to the water.
(We have a header tank and a hot water cylinder, 70's ex council house, trianco was in from then)
Please help! I'm using a tonne of coal and not getting very warm!
Some circulation pumps have a 3 phase mixing valve (cold,warm,hot) to regulate the water pressure in the building; no way to know unless you trace the plumbing. Basically, the hot water temperature could be lost because the circ-pump is cooling it with the cold water supplied to it. This is used to balance the pressure (aka Pressure Balancing Circ-Pump), so heater is really working overtime to heat the water. If the pump has two in and one out that's more than likely your problem; but you should consult a "old-school" plumber in your area.
